Object [] rename1 = {new Integer(0),new String ("fdsy"),new String ("dsd"), new String ("jyt")};
Object [] rename2 = {new Integer(0),new String ("fdsy"),new String ("dsd"), new String ("jyt")};
ArrayList a = new ArrayList();
a.add(0,rename1);
a.add(0,rename2);
Object [] m = a.toArray();
for(int i = 0 ; i < 10 ; i ++){
System.out.println("a.toArray()[0] = " + m[0]);
}
}
}
其中我想显示m[0]中的各项，该怎么显示？

Object []t = (Object[])m[0];
System.out.println( (Integer)t[0]);
System.out.println( (String)t[1]);

Object []t = (Object[])m[0];
